Design Features 3
KNS1600/R User’s Guide - Rev. A00 Kingston Technology Company
Compliance Standards
The Fast EtheRx Switch complies with the 10/100Mbps functions as defined by
IEEE802.3u 100BASE-TX, IEEE802.3i 10BASE-T, and IEEE802.3 CSMA/CD
Ethernet standards.
Design Features
Switching Function
The Fast EtheRx Switch is basically designed to bridge Standard 10BASE-T
Ethernet networks to 100BASE-TX Fast Ethernet networks and to segment 10Mbps
or 100Mbps network segments.
Auto-Negotiation
Auto-Negotiation provides the means of automatically establishing a link by
detecting the link capabilities of the connected device on the network to select the
best operational mode available (i.e. 10/100BASE-TX selection, half- / full-duplex
mode operation, etc.)
Full-Duplex
Full-Duplex transmission means that dedicated inbound and outbound channels are
established for bi-directional transmission of data. This allows the collision
detection mechanism (CSMA/CD) to be by-passed, thus decreasing transmission
delay normally caused by listening, collisions, and packet resends when operating in
half-duplex mode.
Store-and-Forward Switching
The Fast EtheRx Switch uses a packet-forwarding method called
Store-and-
Forward
, which minimizes the re-transmission of faulty data packets. This means
that the Fast EtheRx Switch can store the incoming frame in an internal buffer and
check the packet for errors before sending it out to the destination port. If the frame
does contain errors, it will be discarded and then retransmitted.
Flow Control
The Fast EtheRx Switch implements a collision-based flow control mechanism that
reduces the risk of data being lost at the congested ports. This is accomplished by
forcing a collision with the data frames on all ports once the free-buffer queue has
reached the pre-set minimum.

Hardware Installation
Before you begin installing network cables, please take a few moments to
familiarize yourself with Fast EtheRx Switch. The functions on the front and
rear panels are illustrated in the following sections.
Fig. 1-KNS1600/R Front Panel
Front Panel
Power LED
The PWR LED indicates the power status of the Fast EtheRx switch. The LED
will light up steady green when the AC power cord is connected to the unit
from a power source and the power switch on the unit has been turned on.
100BASE-TX (100TX) LED
The 100TX LED will automatically light up when 100Mbps operation is
detected. This LED will not light up if 10Mbps operation is detected.
LINK/ACT LED (for both 10 and 100Mbps)
The LINK/ACT LED uses a single LED to display two functions. A steady
green light indicates that a good link has been established, and a flashing green
light indicates when data is being received or transmitted. If the LED does not
display solid green indicating a good link, check the following:
1. Make sure that the power is turned on for both the Fast
EtheRx Switch and the attached device.
2.
Verify that the drivers for the network adapter have been
loaded on the PC. Some network adapters require that the
driver be loaded before establishing a proper link.
Front Panel 5
KNS1600/R User’s Guide - Rev. A00 Kingston Technology Company
3.
Make sure the cable is wired properly and connected on both
ends.
4.
Make sure the correct cable type has been selected.
5.
If steps 1 through 4 are correct, please check the cable, as it
may be defective or wired incorrectly. Replace the cable and
try again. Please refer to Appendix A for Pin Assignments
and Appendix B for Cabling Guidelines.
Full Duplex and Collision LED
The FDX/COLL LED uses a dual color LED to display two functions. A solid
green light indicates that Full-Duplex operation has been detected. A flashing
amber light indicates that a collision has occurred in half-duplex mode. Full-
Duplex mode is auto-negotiated on all UTP ports.
UTP Ports
The Fast EtheRx Switch has sixteen (16) 10/100Mbps UTP ports that auto-
negotiate 10/100BASE-TX connections and half- or full-duplex mode
operation. The last UTP port has two RJ-45 port connectors for support of
UTP cabling in the crossover or straight-through wiring configuration. Only
one of the two ports may be utilized.
The RJ-45 port marked
is internally crossed like all other UTP ports. By
default, all repeater and switched UTP ports are generally configured as
standard MDI-X, or internally crossed ports. With a straight-through cable, this
port can be used for cascading to a standard MDI device, such as a network
adapter or router. With a crossover cable, this port can be used for cascading to
another MDI-X device, such as a hub.

Notes on MDI and MDI-X
MDI (Media Dependent Interface) is the standard that defines the mechanical
and electrical configuration of a UTP port. For any two devices to
communicate with each other on the network, the transmitter of one device
must be connected to the receiver of the other device. This can be achieved by
using a crossover cable, or by using the MDI-X port, which implements the
crossover internally.
Ports 1 through 15, like all normal hub ports, are configured as MDI-X. Port 16
supports both MDI and MDI-X configurations. All NICs (Network Interface
Cards) and Router ports are usually by default configured MDI.
Note: Do not use both ports labeled port 16, only one connection can be used.

UTP Cable Wiring Standards
There are two governmental agencies: the Electronic Industry Association
(EIA) and the Telecommunications Industry Association (TIA), which set the
standard for all cable wiring requirements for commercial buildings.
With the advent of 100Mb/s networking products, it is best to use higher
quality CAT 5 cables like Belden or Helix as well as CAT 5-compliant patch
panels, patch cables, and connectors while following the EIA/TIA wiring
standards. 100 Ω UTP CAT 5 type cables use 4-pair UTP wiring.
Refer to the illustrations below for 4-pair wiring using either T568A (Fig. B-1)
or T568B (Fig. B-2) wiring standards. Both T568A and T568B wiring is
compatible with 10BASE-T and 100BASE-TX and require no special
configurations, but for premise wiring, stick to one wiring standard. Mixing
T568A and T568B wiring schemes may cause or lead to potential problems.

UTP Cable Rating Codes
UTP cables meet different UL-NEC requirements based mostly on cable-jacket
quality. Below is an explanation of the rating codes for each cable type.
UL – The National Electrical Code (NEC), published by the National Fire
Protection Association (NFPA), details advisory safety considerations for
electrical wiring. NEC Article 800 Communications Cables are manufactured
to meet these different cable types.
1.
CMP – Cables meeting type CMP requirements are suitable for
installation in ducts and plenums without the use of conduit. These cables
are designed for fire resistance and low-smoke and toxin producing
characteristics.
2.
CMR – Riser type cables are engineered to prevent the spread of fire from
floor to floor and are suitable for vertical shaft applications.
3.
CM – Cables for general building wiring. CM cables are used in areas
other than plenums and risers. These cables are resistant to the spread of
fire and pass the UL 1581Vertical Tray Flame Test.
4.
MP, MPR & MPP – Within Article 800, the Multi-purpose Cables
Category, allows conditional substitutions between different cable types &
are restricted by number, AWG size and stranding of the cable conductors.
Terms You Should Be Familiar With
1.
BACKBONE WIRING – The physical/electrical interconnections
between telecommunications wiring closets and equipment rooms.
2.
COMPLIANCE – A datacomm or wiring device that meets all
characteristics of a standard is said to be in compliance with that standard.
3.
PREMISE WIRING – The entire wiring system on the premises,
especially the supporting wiring that connects the communications outlets
to the network interface jack.
PJ
NEAR-END CROSSTALK (NEXT) – In wires packed together within a
cable, the signals generated at one end of the link can flush out the weaker
signals coming back from the recipient.

Appendix D Frequently Asked Questions
What is a switch and what does it do?
Switching hubs are low-latency devices that allow you to maximize the
bandwidth of a network using concurrent access within the unit. Switches
allow you to segment LANs, connect LANs of different speeds, or extend the
collision domain of an existing LAN.
What’s the difference between a repeater and a switch?
A repeater is a device that extends the diameter of a network by regenerating
and forwarding received Ethernet packets. It repeats incoming signals to all
other ports on the device.
Like a repeater, a switch can also extend the diameter of a network. However,
a switch can also extend the collision domain of a network, like bridging a
10Mbps Ethernet LAN with a 100Mbps Fast Ethernet LAN. See the
illustration below. A switch can also be configured to operate in half-duplex or
full-duplex mode, whereas a repeater can only operate in half-duplex mode.
